THE RELATIONSHIP BETWEEN PROLACTIN LEVELS AND THE RESULTS OF HOLTER MONITORING IN PATIENTS WITH STABLE ANGINA OF TENSION AND GASTROESOPHAGEAL REFLUX DISEASE

Abstract

The aim: Determine the possible relationship between prolactin levels and the results of Holter monitoring in patients with stable angina of tension and gastroesophageal reflux disease (GERD). Materials and methods: The study included 118 patients with stable angina of tension of I-II functional class. Of these, 88 patients with stable angina of tension with comorbid GERD (A, B, C), who were included in the second group of the study and 30 patients with isolated stable angina of tension which formed the 1st group. All patients who were included in the study prior to treatment were evaluated for serum prolactin levels and Holter monitoring. Results: In patients with stable angina of tension and GERD, prolactin levels exceed the norm levels and are higher than the level of prolactin in the group with isolated stable angina (p<0,05), as well as the number of episodes of painful and painless myocardial ischemia and their duration (p<0,05). The presence of a comorbidity with GERD provokes an increase in the total duration of episodes of ischemia per day in patients with stable angina compared to those in patients with no GERD. A direct linear relationship was founded between prolactin serum levels and the number of episodes of pain in myocardial ischemia in patients with stable angina and GERD per day, and between the total duration of episodes of myocardial ischemia and prolactin levels. Conclusions: In patients with stable angina and GERD, in 70.4% of cases, the level of prolactin exceeds the norm in 2,6 times, and is higher than the level of prolactin in the isolated group of stable angina. For the comorbidity of stable angina and GERD, the number of episodes of painful, painless myocardial ischemia and their duration is more than once in the group of patients with stable angina without GERD (p<0.05).
